This house is treated with a non-toxic glaze and is therefore optimally protected against the elements. To maintain this protection, we recommend painting the wood every 1-3 years with a non-toxic wood glaze or paint (water-based, suitable for outdoor use). You should regularly inspect the house for signs of chafing on the inside and repair the affected areas as necessary, so that your animals remain well protected and safe in the house. This way, you and your little ones can enjoy the small animal home for a long time.
